HOT-AIR REGISTER.

SPECIFICATION forming part of Letters Patent No. 773,068, dated October 25, 1904.

Application filed .Tune' 1, 1903. Serial No. 159,399. (No model.)

To ctZZ whom it may concern: 1

Be it known that I, CHARLES H. FosTER, a citizen of the United States, residing at'the city of Omaha, county of Douglas,State of N ebraska, have invented a certain new and useful'Hot-Air Register, of which the following is such a full,'clear,and exact description as will enable any one skilled in the art to which it appertains to make and use the same, refer encebeing had to the accompanying drawings, forming. part of thisspecification. My invention relates to hot-air registers, and more particularly to that class of registers known as side-wall registers, which are placed in a substantially in the wall ofa room in place of inithe floor.

My invention consists in part in thecombination, with a frame provided with a valveopening, of a valve'having one end pivoted 10 is the frame or adjacent to the top of said opening, a slidinglyemounted grille, and connections'between said grille and. valve for moving .the latter. r

I My invention also consists in various other novel features-and details of construction, allof which will be described in the following specification and pointed out in the claims aflixed hereto. I

In the accompanying drawings, which illustrate one form of register made in accordance with my invention, Figure '1 is a front elevation. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a section through the'frame, taken on the line 3 3 of Fig. 4:. Fig. l is a verticalcentral section on the line 4 4L of Fig.

1. Fig. 5 is also a vertical central section,

butshowing the register in position in the wall. Fig. 6 is a rear view of a portion of the register, and Fig. 7 isan isometric projection of a portion of the grille.

' Like marks of reference 'refer' to similar parts in the several views of the drawings.

border of the register. This frame or border 10 is adapted to rest against the base-board 11.

' The reference character 12 designates the plaster, and 13 the lathing "of the, wall. Formed in the frame or border 10 is a valveopening 14''. Projecting rearwardly from the frame orborder 10 are two vertical flanges 15 the top of the vertical position the upper ends of the and a cross-flange 16. The vertical flanges 15 are at right angles-to the frame or border, while the cross-flange 16, extending across register, is preferably somewhat inclined, as best shown in Figs. t and 5.

.The lower end of the frame or border 10 projects some distance from the wall, as best shown in Fig. 5. Formed on the flanges 15 and extending into the opening 14 are ribs 17, and 18, each of said ribs being preferably composed of a plurality of sections. The rear edges of these ribs 17 and 18 form shoul- 'ders against which the valve 19 is adapted to is in its closed position. "The upper end of the valve 19 is bent around a rest when the valve wire or rod20. This wire or rod 20 rests upon ribs 17 and 18. At the central portion of the flange 16 is formed a downwardly-projecting lug 21, in which is formed a'notch adapted to receive the upper coiled end of the valve 19. The valve is prevented from coming out of the front of the valveopening by means of downwardly-projecting tion 23 for convenience in castin the border.

The valve 19 is preferably provided with a slot 24 for the reception of the corner of the lug 21 when the valve is in its open position,

as shown in Fig. 5. The reference character 26 designates the grille,'which is composed of two sets of bars or and arranged in different'planes. These two sets of bars or rods are connecteda'nd preferably formedintegral. with two knuckles 27, by means of which it is detachably pivoted to the valve 19. ranged adjacent to the lower end of the grille 26 is an auxiliary grille 28, which is either rods crossing each other rib 22. This rib 22 has a central cut-away por- The grille 26 is provided 2 rigidly secured to or formed integral with the frame or border 10. This auxiliary grille 28 is provided with detents 29, adapted to engage with teeth 30, formed on the lower end of the grille 26 in order in its raised position. The grille 26 is, also provided with a forwardly-projecting portion 31, which serves as a handle for raising and lowering the grille. The upper end of the grille 26 is provided at each side with a projection 32, which projections are adapted to 7 pass through openings 33 in the ribs 17 and to maintain the grille 18 hereinbefore described. Below these openings 33 the said ribs are provided with inclined portions 34, upon which the said projections 32 rest when the valve is in its closed position. These projections when thus resting upon the inclined portions 34: act as trunnions and enable the weight of the grille 26 to hold the valve 19 firmly against the ribs 17 and 18, as shown in Fig. 4. The rib 17 is provided with an offset portion 35, as shown in Fig. 5. This offset portion 35 is adapted to cooperate with a lug 36, so as to normally prevent the lower end of the said grille from being swung out of the valve-opening 1 1. The reference character 38 designates the flue-pipe, which is provided with flanges 39, forming the flue-opening and surrounding the flanges 15 and 16 of the valve-opening. In order to guide these flanges 39 into position and to hold them close to the flanges 15 and 16 hereinbefore described, I provide the frame or border 10 with a number of guidelugs 40. Each of these guide-lugs is provided with an inclined V- shaped face 41, which is directed toward the flange on the border 10.

When the grille 26 is in its lowest position, as shown in Fig. 4, the valve 19 will be held firmly against the shoulders formed by the rear edges of the ribs 17 and 18, and thus completely and effectively close the valveopening 14:. When, however, it is desired to open the valve 19, the grille 26 is raised by means of the handle 31, so as to cause the teeth 30 on the lower side of the grille to engage with the detents 29 on the upper end of the auxiliary grille 28. This will swing the valve 19 out into the flue-pipe 38. By continuing the upward movement of the grille 26 the valve 19 can be swung completely across the pipe, as shown in Fig. 5. By the engagement of the lug 36 with the offset 35 of the rib 17 the grille is normally kept from swinging out of the valve-opening. When, however, it is desired to detach the grille 2.6, the said grille is forced toward the left-hand side of the opening. This is permitted by means of the resiliency of the valve 19, which is preferably formed of sheet-steel. As soon as lug 36 is disengaged from the rib 17 the grille can be swung forward and upward. The form of the knuckles 27 is such that when this is done they become detached from the valve 19. The valve 19 can also be detached from the border or frame by forcing the central part of its upper end downwardly, so as to disengage it from the lug 21. By forming the grille of two sets of bars or rods arranged in different planes I secure a greater amount of opening in the grille, and thus am enabled to discharge the full Volume of air from the flue-pipe 38.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is
